remove patch_private_key, as it doesn't make any sense 
In particular, we were patching the EdDSA private keys, which are
*hashed* before doing the curve multiplication.  Thus clearing the bits
*before* the hashing doesn't make any sense at all.  These bits are
cleared anyway when deriving the public key.

cdcd67a27d Use KDF better 
We now send the secret_seed to the skm variable, while sending the
counter salt to the xts variable.  I have not check this with
http://eprint.iacr.org/2010/264 but it seems correct.

Indeed rsa_blinding_key_derive places the strong source of
randomness in skm too, and uses a constant string for xts.
